Concrete Slender Wall Design – Back To The Future, John W. Lawson, James Lai 2010 California Polytechnic State University - San Luis Obispo

Concrete Slender Wall Design – Back To The Future, John W. Lawson, James Lai

Architectural Engineering

Slender concrete walls incorporated into tilt-up construction
over the past 60 years have performed remarkably well under
out-of-plane wind and seismic loads. While issues associated
with seismic wall anchorage gave this form of construction a
black-eye in the early days, the concrete walls themselves
have always performed very well even as far back as their
first use in the early 1900s. Yet the height-to-thickness
limitations in 1985 and earlier model building codes were
proved irrational and were removed. We as engineers expect
building codes to evolve and advance the state of the art with
each successive edition. The latest edition ...

Ab-10-018: The Effects Of Noise From Building Mechanical Systems With Tonal Components On Human Performance And Perception (1322-Rp), Erica E. Ryherd, Lily M. Wang

Architectural Engineering -- Faculty Publications

This study investigated the effects of noise from building mechanical systems with tonal components on human task performance and perception. Six different noise conditions based on in-situ measurements were reproduced in an office-like setting; all were set to approximately the same sound level (47 dBA) but could have one particular tonal frequency (120 Hz, 235 Hz, or 595 Hz) at one of two tonal prominence ratios (5 or 9). Thirty participants were asked to complete typing, grammatical reasoning, and math tasks plus subjective questionnaires, while being exposed for approximately 1 hour to each noise condition. Results show that the noise ...


Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau 2010 University of Nebraska-Lincoln

Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau

Architectural Engineering -- Faculty Publications

Minimization of the sound pressure field within the shadow zone of a noise barrier is achieved by reducing the pressure gradient along a line, at the top of a barrier, via active noise control. The noise control effectiveness of a barrier is increased by this strategy, especially for specific system configurations. The proposed method was evaluated by numerical simulation. Results indicate that system orientation has little effect on minimizing the pressure gradient at the top of the barrier when the error sensors are invisible to the primary noise disturbance. Highly effective control within the shadow zone and close to the ...


Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau 2010 University of Nebraska-Lincoln

Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau

Architectural Engineering -- Faculty Publications

Predicting the insertion loss of an opening backed with an enclosed space is important for building noise control. Recent research in sound transmission through apertures of finite depth in infinite rigid baffles has included the effects of propagating and evanescent modes within the aperture in order to extend models to higher frequencies. The present study extends the model to the case of the aperture backed by a cavity as opposed to sound radiating into half-space. The role of coupling between the aperture modes, radiation modes, and cavity modes in the transmission was investigated. The results were compared to those of ...


Optimum Absorption And Aperture Parameters For Realistic Coupled Volume Spaces Determined From Computational Analysis And Subjective Testing Results, David T. Bradley, Lily M. Wang 2010 University of Nebraska-Lincoln

Optimum Absorption And Aperture Parameters For Realistic Coupled Volume Spaces Determined From Computational Analysis And Subjective Testing Results, David T. Bradley, Lily M. Wang

Architectural Engineering -- Faculty Publications

This project utilizes computational modeling to study the effects of varying two architectural parameters, absorption ratio and aperture size, in a realistic coupled volume concert hall. Coupled volumes have been shown to exhibit non-exponential sound energy decay profiles, referred to as double slope effect. A number of objective metrics (T30/T15, LDT/T10, decay ratio, and ΔL) have been used to quantify the double slope effect of the profiles generated in the virtual hall. T30/T15 and LDT/T10 showed similar trends across all hall configurations, indicating decreasing double slope effect with increasing coupled volume absorption ratio for each aperture ...

Re-Designing The 'Great Australian Dream': Creating A More Sustainable Housing Future., Eko Pam 2010 Edith Cowan University

Re-Designing The 'Great Australian Dream': Creating A More Sustainable Housing Future., Eko Pam

Theses : Honours

Sustainable design is a buzzword in the field of architecture, yet very few houses built in Western Australia last year had an environmentally friendly focus. Through much debate and research, designers now have a thorough understanding of the environmental impact ofhousing (Kibert, 2005; Roaf, 2001; Yeang, 1995). The result is that architects worldwide are now offering a more sustainable housing model. These houses are expensive and look very different to the popular project homes. Despite this environmental awareness, the homes Western Australians build appear to be growing larger, with little regard for their future sustainability. There is reluctance among Australians ...

The impact was measured in relation to the Metropolitan Statistical Areas corresponding to the 18 ballparks included, specifically looking at the impact on employment rates and per capita personal ...


Managing An Unstable Housing Market, Brendan Williams, Brian Hughes, Declan Redmond 2010 University College Dublin

Managing An Unstable Housing Market, Brendan Williams, Brian Hughes, Declan Redmond

Articles

Abstract
In this paper it is intended to place the recent experience of the Irish housing market in the context of economic and property market cycles, how these interact over a property cycle and lessons from recent policy experience including interventions in the housing area. In spatial terms the current
housing market can be seen as the result of an ad-hoc development led urban growth pattern which contributed to a dispersed development pattern with problems in oversupply. It is clear that alternative options exist to this approach and that evidence based management systems in terms of planning, development and financial ...

Nourishing Urbanism: A Case For A New Urban Paradigm, Lewis Knight, William Riggs 2010 Gensler

Nourishing Urbanism: A Case For A New Urban Paradigm, Lewis Knight, William Riggs

City and Regional Planning

True sustainability demands that we seek to more than ‘prop up’ traditional approaches to our environment; rather, it requires that we redress current shortcomings in the planning and design of our urban environment at both bio-regional and local scales. Nourishing Urbanism proposes a shift in the urban and non-urban paradigm relating to energy, water and food; all face significant climate-related challenges—and are united by land-use policy, planning and design. We need a renewed planning and design framework for cities and regions that allows the retrofitting of today's urbanity, and prepares our cities for a new tomorrow. Nourishing Urbanism ...


Challenging Computer Software Frontiers And The Human Resistance To Change, Jens Pohl 2010 California Polytechnic State University - San Luis Obispo

Challenging Computer Software Frontiers And The Human Resistance To Change, Jens Pohl

Architecture

This paper examines the driving and opposing forces that are governing the current paradigm shift from a data-processing information technology environment without software intelligence to an information-centric environment in which data changes are automatically interpreted withinthe context of the application domain. The driving forces are related to the large quantity of dataand the complexity of networked systems that both call for software intelligence. The opposing forces are non-technical and due to the natural human resistance to change.


Based on this background the paper describes current information-centric technology, proposes avision of intelligent software system capabilities, and identifies four areas of necessary ...


When Economic Growth Is No Longer The Norm: Teaching Urban Design In A Time Of Transformation, Sujata Shetty, Andreas Luescher 2010 University of Toledo

When Economic Growth Is No Longer The Norm: Teaching Urban Design In A Time Of Transformation, Sujata Shetty, Andreas Luescher

Architecture and Environmental Design Faculty Publications

Over the past few years, there has been increasing interest in cities that are rapidly losing population, so-called shrinking cities. This is becoming a global phenomenon, with shrinking cities found on every continent. The decline has been attributed variously to changing demographics, suburbanization, postsocialist transformation and deindustrialization. We are just beginning to develop approaches to dealing with shrinkage and its consequences – vacancy, abandonment, and limited public and private resources. However, there is currently little faith in the ability of design-related disciplines to deal with shrinking cities. Some authors argue that disciplines such as architecture, urban design and urban planning have ...
